The Navy type CMX-46159 is better known as the TCS-12 receiver. The TCS was
designed by Collins and used, along with its matching transmitter and a power
supply, during World War II on LST landing craft, P-T boats, and a variety of
other smaller boats as well as on-shore applications. This unit was assembled
for Collins .Frequency coverage is 1.5
to 12 MHz in three ranges. The receiver may be tuned and operated with either a
variable master oscillator or at fixed frequency using one of four switch-selected
pluggable crystal units. Each of those crystal units contains two crystals. One
crystal is at 455KHz higher than the selected frequency for the superhet
oscillator and the other is at the selected frequncy for use in spotting. The
receiver has 7 tubes including a 12SK7 for RF amp, two 12SK7 for IF amps, 12SA7
for converter, 12SQ7 for detector and BFO, a 12A6 for master and crystal
oscillator and another 12A6 for audio output. The antenna for which the TCS is
designed is a 20 foot
whip. Connections to the transmitter, power supply and accessories are by an 11
pin connector.

"Krusik" Valjevo factory. In the Yugoslav People's Army generally is
used for link beetwen Yugoslav Army units end Territorial defence units. Since
its introduction to its cancellation, it hasn't been used much in the mobile
links of the Yugoslav Army, because all other radio devices (RUP-12, RU-2,
RUT-1...) were working in this range using frequency modulation (FM), so a
mutual connection was possible only between these two RT-20-TC6 devices, or
with other compatible devices, like radio sets type: RT-1-T4, RT-1-T600 and
RT-20-TM produced by "Iskra" factory, but they were used in
Territorial defense units. Technical

In
the introductory page, we emphasize that we will not describe the radio devices
created before and during World War II, this HF radio receiver, produced in
Germany in 1936. however, deserves to be found on this page. Receiver was mass
produced for the needs of the German army, and in 1945. on this device was done
more modification. (The device described here is a version from 1943.) In the
arsenal of Yugoslav Army it was found as war booty in 1945. which is by the
first repair in Yugoslav workshops winner had to emphasize with writing on the
box:"captured
16962 devices". In Yugoslav Army receiver is used in
conjunction with the transmitter or independently. The device was dropped from the
fifties of the Yugoslav Army equipment. Radio receiver TORN Eb was intended for
receiving AM telephony and telegraphy (CW) in the frequency range of 0.097 MHz
to 7.095 MHz. This frequency range was divided to 8 frequency band that was
chosen by the switch a fine set frequency was within continuous. By the
construction receiver was super-reaction and in its was built 4 German vacuum
tube RV2P800.
The first tube was made from 1 VF intensifier, and the other from 2 VF
intensifier, third AM detector and the fourth tube was AF intensifier .As in
all other super-reaction receiver, receiver sensitivity and selectivity was
regulated by the introduction of positive feedback couple that was setting with
special button . The device was put in two metal container and in the top
container was receiver, in the lower container was battery, vibrators
converter, wire antenna and headphones. Device was powering on from battery
voltage of 2 VDC - 0.8 A,
over vibrators converter or anode battery of 90 VDC - 10 mA. There was versions
in which was changed converter to ensure supply with voltage of 12 V from the

version is designated as model 51S-1F.
The rack-mounted DC version is designated as model 51S-1AF. The 51S-1B is
similar to the 51S-1, but it has a rear-mounted junction box that provides
military-type connectors for power, control, audio, and antenna lines.

Radio
set SCR-284-A
was produced by the United States in 1944. The Yugoslav Army have got this
radio device in the package of military assistance that provided the United
States after the World War II. It is interesting that the United States, have
not just Yugoslav given this device as military assistance, the device could be
found in the Soviet Red Army. This radio device the U.S. Army last used in the
war in Korea , and later the army withdrew device from the use because of
outdated. Radio set SCR-284-A, in its time, was known as very high-quality and
compact device. The base of the device was made from transceiver BC-654-A .
Depending of the configuration of set their was the transport option for
installation in the vehicle and pack unit for the transport by man or horses.
